piles up to a maximum depth of 20 m over its entire route. The single column system will be composed of four cast-in-place piles with a diameter of 1.0 m and a footing of 4.5 m (length) x 4.5 m (width) x 1.5 m (thickness), and a portal brace rigid frame system of four cast-in-place piles with a diameter of 0.8 m at a footing of 3.7 m x 3.7 m x 1.4 m at both ends.
Due to geographical conditions at the site, special T-type supports will be used at eight places.
(2) Girder (Appendix 6.1-1, 2)
The basic structure is a continuous trapezoidal box type girder composed of 25-m prestressed concrete (PC) beams for two single-track lines. Beam length will be extended to 30 m at six places.
The aspect ratio of girder cross section is 2.22 with a maximum length of 4.0 m in the horizontal direction and 1.8 m in the vertical direction.
Under the basic design, the entire route is composed of two single track girders.
However, double-track girders will be used under some conditions.
6.2 Station Plan
(1) Classification of Stations by Function
The Bangalore LRT network will have a total of 87 stations. Stations are divided into three functional types in relation to neighboring areas.
(a) CBD/Commercial Stations
These stations are located where there are large numbers of commercial,business and governmental facilities. People will walk to such facilities from the stations. Parking lots are not necessary.
(b) Community Stations
These stations are in medium-sized commercial and business areas or residential districts. Passengers use buses, taxis or rickshaws, so bus stops or parking lots are required.
(c) Regional Stations
These stations function independently and serve as area transportation hubs.
Surrounding areas normally have development potential, which should also be taken into consideration.
Each station has been designed according to its function.
With respect to their facilities, entrance are provided to 85 stations, drop-off to 40
